Abstract: In view of the problem that diode rectifying circuit ca't realize bidirectional flow of energy, the paper proposed a design scheme of energy feedback VSR. On the basis of topology of main circuit and mathematical model of three-phase VSR, it analyzed control principle of the energy feedback VSR in details, and introduced implementation of improved SVPWM algorithm. At last it built simulation model in Matlab/Simulink. The simulation result showed that the VSR has good stability and quick dynamic response speed and realizes bidirectional flow of energy.
